c. Minesweeper Minesweeper [3] is a single-­­player puzzle video game. The objective of the game is to clear a rectangular board containing hidden "mines" without detonating any of them, with help from clues about the number of neighboring mines in each field. The game originates from the 1960s, and has been written for many computing platforms in use today. Write a VBA Sub Program to create a Minesweeper game. Create a 5 X 5 board for the game. Remember you are the person who creates the game board for others to play on. ENGR 1412 Introduction to Computer Programming Dr. Jennifer Glenn, Summer ‘17 Here are the rules that you need to keep in mind while building the game: a. Out of the 25 cells, 10 cells should contain mines and others contain no mines. (Hint: Generate 10 random non-­­repetitive numbers and place the mines in those cells). b. If a player selects the cell that contains a mine, the player loses. If the cell contains no mine then the cell should display the number of mines surrounding the cell (any cell which has at least one corner touching the currently selected cell is said to be surrounding the current cell). c. If there are no mines in any of the cells surrounding the cell the player selected, then the player’s selected cell plus all the surrounding cells should open up. Any game board encourages people to play if it looks creative and attractive. Design your game using your best creative skills so people will want to play your game!.
